The 123\TUNE-4-R-V-G replaces most 4 cyl. Lucas-distributors for engines in Great-British (hence ‘GB’) cars.

Please check if the distributor need a connection for a mechanical rev.counter, as a 123\TUNE-4-R-V-G does not offer this.

If you want to tune your engine, or you have an engine for which there is no standard distributor available….. And you are a Windows PC user, the 123\TUNE is the answer! By connecting it to a computer, you can easily adapt the 123\TUNE to fulfill even the most demanding requirements. The unit offers two sets of curves that can be selected by placing 12 Volt on a wire from the 123\TUNE. Handy, if you’re driving on two different fuels, like regular fuel with LPG or with Ethanol
